This work first discloses a new strategy for amine activation to give reactive amine anion by in situ generated iminium cation-amine anion pair through decomposition of sterically hindered aminals. Utilizing this strategy, a highly regio- and chemoselective cyclocarboamination of ortho-formyl phenylacetylenes with secondary amines has been realized under metal-free mild reaction conditions. The cyclocarboamination with notably tunable product profiles depends on the separation and purification procedure, a diverse range of 1, 3-diamino-1H-indenes (essentially reactive enamines) and 3-amino-1-indanones were obtained, respectively. Moreover, using iodine as an electrophile to couple with various ortho-formyl phenylacetylenes and secondary amines, a series of 3-amino-2-iodo-1-indanones were efficiently achieved with four bonds (C=O, C-C, C-N and C-I) formation in an one-pot three-component reaction. These results demonstrated an unprecedented methodology for the construction of highly functionalized 1H-indene and 1-indanone compounds.

DNA encoded libraries (DEL) have shown promise as a valuable technology for democratizing the hit discovery process. Although DEL provides relatively inexpensive access to libraries of unprecedented size, their production has been hampered by the idiosyncratic needs of the encoding DNA tag relegating DEL compatible chemistry to dilute aqueous environments. Recently reversible adsorption to solid support (RASS) has been demonstrated as a promising method to expand DEL reactivity using standard organic synthesis protocols. Here we demonstrate a suite of on-DNA chemistries to incorporate medicinally relevant and C-S, C-P and N-S linkages into DELs, which are underrepresented in the canonical methods.

Metal-catalyzed beta-C-H functionalization of saturated carbonyls via dehydrogenative desaturation proved to be a powerful tool for simplifying synthesis of valuable beta-substituted carbonyls. Here, we report a copper-catalyzed dehydrogenative gamma-C(sp(3))-H amination of saturated ketones that initiates the three-component coupling of saturated ketones, amines and N-substituted maleimides to construct polysubstituted anilines. The protocol presented herein enables both linear and alpha-branched butanones to couple a wide spectrum of amines and various N-substituted maleimides to produce diverse tetra- or penta-substituted anilines in fair-to-excellent yields with good functional group tolerance. The mechanism studies support that this ketone dehydrogenative gamma-C(sp(3))-H amination was triggered by the ketone alpha,beta-dehydrogenation desaturation that activates the adjacent gamma-C(sp(3))-H bond towards functionalization. This alpha,beta-dehydrogenation desaturation-triggered cascade sequence opens up a new avenue to the remote C(sp(3))-H functionalization of saturated ketones and has the potential to enable the rapid syntheses of complex compounds from simple starting materials.

Oxidative carbonylation using CO/O-2 is an attractive strategy to construct carbonyl compounds, but the explosive limit of the gas mixture hampers its application. Now, this safety issue is overcome in the aminocarbonylation of alkynes by replacing the external oxidant O-2 by electrochemistry facilitating a mild and safe reaction. Palladium-catalysed oxidative carbonylation using oxygen as the oxidant is an economical approach; however, the gas mixture of CO and air has an explosive limit of 12.5-74.0% that could hamper extensive application of this process. Herein we report an electrochemical aminocarbonylation of alkynes under atmospheric pressure in an undivided cell without an external oxidant. The transformation has a broad substrate scope (83 examples) that involves primary amines and ammonium salts. Furthermore, mechanistic studies through cyclic voltammetry, in situ infrared and quick-scanning X-ray absorption fine structure spectroscopy reveal the reasons for this protocol proceeding smoothly under electrochemical conditions.

A Cu-catalyzed dearomative amination of simple phenols with O-benzoylhydroxylamines (R’RN-OBz) to synthesize alpha-aminocyclohexa-2,4-dienones is reported. This intermolecular transformation occurs exclusively at the position ortho to the hydroxyl group, providing a convenient method to synthesize the desired products in high yields. The reaction proceeds under mild conditions and tolerates a wide range of functional groups. Mechanistic studies indicate that this transformation proceeds via either (1) a single-electron transfer process involving attack of an N-centered radical onto the phenol or (2) a two-electron pathway involving addition of phenol to an electrophilic Cu-III-amino complex via an inner-sphere process.
